Analysis and solution of daily failure of precision pressure gauge

The precision pressure gauge is composed of a connector, a spring tube, and the movement. The welding of precision pressure gauges mainly includes lead-zinc welding, silver welding, argon arc welding, special welding, etc. The normal operation of the clarinet of the instrument is 100,000 times. Its ... read more

Several situations of failure of precision pressure gauges

The performance of the precision pressure gauge is relatively superior. Generally, there are few problems during the operation, but sometimes it will cause failures due to improper operation. Today, this article will briefly analyze the reasons for the failure of the precision pressure gauge. 1. If ... read more

Definition and selection of pressure gauges for different pressures

1. Pressure gauge Take the pressure zero as a reference, the pressure higher than the pressure zero. 2. Positive pressure gauge The pressure is higher than atmospheric pressure based on atmospheric pressure (gauge pressure zero, the same below). 3. Negative pressure (vacuum) meter The pressure is le... read more

How to install the precision pressure gauge correctly

The installation position of the precision pressure gauge should meet the requirements of the installation state. The dial should generally be in a vertical state, and the position should be suitable for observation by the staff. At the same time, the tightness should be ensured and no leakage shoul... read more

What are the common failure problems of precision pressure gauges

1. The precision pressure gauge has no indication (the pointer does not move); (1) The spring tube or pressure guiding tube is blocked; (2) The stop valve is not opened; (3) The transmission mechanism fails or jams; (4) Air leakage. 2. The pointer moves sluggishly; (1) The pointer touches the glass ... read more
